Abstract
A method of overcoming the problems of measuring the exhaust flow during pulsating and reversing flow by placing a “box” in series within a few feet of the connecting pipe to serve as a filter. The box is constructed with soft expandable sides, so it can expand with the pressure pulsations and then contract, creating a very smooth flow that can be measured with a measuring device at the exit of the flow from the box.
